A blood clot can present as a warm-to-the-touch painful swelling in an arm or leg, or if the clot moves to the lungs, it can be accompanied with chest pain, a hard time breathing, fainting, fever and a cough both with and without blood, according to the U.S. Department of Health and Human Services. If any of these symptoms arise, call 911 or visit an emergency room immediately.
While leg, arm and lung blood clots are the most common, they can also occur in the brain and abdomen and these types of blood clots present with visual disturbances and seizures or severe abdominal pain, diarrhea and vomiting, respectively, according to the American Society of Hematology.
If experiencing any of these symptoms along with any risk factors for blood clots such as recent surgery or broken bones, immobility due to bed rest or long periods of sitting, the use of hormone therapy or birth control pills, presence of a clotting disorder or obesity, a blood clot will be suspected, according to Harvard Health Publications. Prevention is key to preventing blood clots and staying active throughout the day, even if this just means moving the legs around while sitting, is beneficial in preventing blood clots, according to Harvard Health Publications.
